NESTLE

NESTLE is a few-group neutron diffusion equation solver utilizing the nodal expansion method for eigenvalue, adjoint, fixed source steady-state and transient problems. The code was developed at North Carolina State University beginning in the late 1980’s. In recent years, the University of Tennessee and ORNL have collaborated to expand NESTLE’s capabilities. The code is being restructured into a modular modern Fortran program that is fully compatible with the SCALE code system.
